RESUMEN
BACKGROUND/PURPOSE: Perfluorocarbon heavy liquid (PFCL) is used in vitreoretinal surgery to flatten the unsupported detached retina before insertion of silicone oil in cases of giant retinal tear or relaxing retinectomy. Direct exchange of PFCL for silicone oil is recommended to reduce retinal slippage when compared with fluid-air exchange, but it is commonly regarded as a difficult procedure. We describe our technique for direct PFCL-silicone oil exchange using a 20-gauge drainage cannula, reliably avoiding the complications of retinal slippage and high intraoperative intraocular pressure. METHODS: We present a consecutive case series of patients undergoing PFCL-oil exchange and explain, using Poiseuille's equation for laminar fluid flow through a cannula, the rationale for using a 20-gauge drainage cannula rather than smaller gauges to avoid high intraocular pressure. RESULTS: Twenty-six patients underwent PFCL-oil exchange from February 1, 2019, to September 30, 2019. There was no intraoperative retinal slippage or pressure-related complications. Postoperatively 20 patients underwent oil removal. Six suffered retinal redetachment, and 14 remained attached. The vision postoil removal ranged from 6/6 to hand movements. CONCLUSION: We are confident that the PFCL-oil exchange technique described here is reliable and safe. The use of a 20-gauge drainage cannula is recommended regardless of vitrectomy gauge.

Introduction: The objective of this systematic search and review was to investigate the role of optometrists in teleophthalmology and digital referral. We examine the implications of the optometric communities' increasing access to advanced imaging, such as optical coherence tomography (OCT), in ophthalmic telemedicine schemes. Methods: A systematic search was conducted, using PubMed and Embase, in April of 2019. Eight hundred eight (n = 808) texts were retrieved and 99 articles were deemed eligible for full-text review. Twenty-six (n = 26) studies were included in the qualitative synthesis. All studies involved optometrists as principal service providers. Results: Findings demonstrate that optometrist-facilitated teleophthalmology results in consistent reductions in hospital referrals and waiting times, as well as high patient satisfaction. Optometrists are identified as crucial to the success of many projects and their access to advanced imaging technology is observed to position optometry practices as the most convenient location to establish a teleophthalmology program. OCT imaging demonstrated the potential to increase diagnostic accuracy and is increasingly prevalent in optometry practice. The importance of additional training for optometrists participating in teleophthalmology schemes is highlighted, as is the need for appropriate remuneration for those involved. Conclusion: The role of community-based ophthalmic care in reducing demands on hospital eye services (HES) is highlighted by our results, demonstrating that optometrist-facilitated teleophthalmology can dramatically reduce referrals and streamline care. In addition, the increasing prevalence of OCT in optometric practice represents an underutilized resource for HES.

(1) Background: Inherited retinal degenertions are rare conditions which may have a dramatic impact on the daily life of those affected and how they interact with their environment. Coordination of clinical services via an ophthalmic genetics multidisciplinary team (OG-MDT) allows better efficiency of time and resources to reach diagnoses and facilitate patient needs. (2) Methods: This clinical case series was conducted by a retrospective review of patient records for patients enrolled in the Target 5000 programme and managed by the OG-MDT, at the Mater Hospital Dublin, Ireland (n = 865) (3) Results: Herein we describe clinical cases and how the use of the OG-MDT optimizes care for isolated and syndromic IRD pedigrees. (4) Conclusions: this paper demonstrates the benefits of an OG-MDT to patients with IRDs resulting in the holistic resolution of complex and syndromic cases. Furthermore, we demonstrate that this format can be adopted/developed by similar centres around the world, bringing with it the myriad benefits.
